Stable carbon and hydrogen isotopic compositions of Paleozoic marine crude oils from the C

A study by the Australian Ocean Data Network focuses on stable carbon and hydrogen isotopic compositions of bulk, saturated, and aromatic hydrocarbons in 17 Paleozoic marine crude oils from the Canning Basin, Western Australia. The data includes bulk isotopic values and n-alkane-specific profiles for three major oil families, used to characterize petroleum systems and compare with other Australian basins. The dataset was last updated on 2026-06-16.

Use Cases

• Characterizing oil families and petroleum systems based on stable isotopic compositions mentioned in the description.
• Investigating systematic changes in bulk stable carbon isotopic composition throughout the Paleozoic era.
• Assessing the influence of water chemistry and thermal maturity on hydrogen isotopic profiles of n-alkanes.
• Comparing isotopic trends between different Australian basins, such as the Canning, Bonaparte, Arafura, and Perth Basins.

Strengths

• Includes data from 17 distinct Paleozoic marine crude oil samples.
• Provides both bulk isotopic values and n-alkane-specific carbon and hydrogen isotopic profiles.
• Enables comparison with other Australian and global marine oils and source rocks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on Western Australian basins.
